The Kolar Gold Field closed in 2001, having produced more than 800t of gold during its 120-year history. 1 During its first two decades of operation (1884-1904) the average grade of the ore produced from shallow underground working was an impressive 45g/t, while over its total life span the average ore grade was 15g/t. By comparison, gold ...
